iOS - Background player for AVPlayer

Replace APPNAME with your own app name!

Add UIBackgroundModes in the APPNAME-Info.plist, with the selection App plays audio

Then add the AudioToolBox framework to the folder frameworks.

In the APPNAMEAppDelegate.h add:

#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>

so it look like this:

...
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
...

In the APPNAMEAppDelegate.m add the following:

// Set AudioSession
NSError *sessionError = nil;
[[AVAudioSession sharedInstance] setDelegate:self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:&sessionError];

/* Pick any one of them */
// 1. Overriding the output audio route
//UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
//AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);

// 2. Changing the default output audio route
UInt32 doChangeDefaultRoute = 1;
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof(doChangeDefaultRoute), &doChangeDefaultRoute);

into

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

but before the two lines:

[self.window addSubview:viewController.view];
[self.window makeKeyAndVisible];

Build your project and see if theres any error, If not, try debug on Device insted of the Simulator, the simulator can bug.

Hope this helps.
